Abstract
The process of laminarization of turbulent flow with heat transfer in a plane confuser with a constant constriction angle is numerically simulated. The effect of the favorable longitudinal pressure gradient on the flow and heat transfer parameters is shown. The results of the calculations are compared with the experimental data on the heat transfer. The value of the acceleration parameter, at which flow in the channel becomes fully laminar, is determined.
